ECOC22 – APDbias
Reclaiming High-Voltage APD Biases From Dropped Optical Data Signals of Multi-Lane Interconnects

As a method to extend the optical budget of intra-datacenter interconnects, we demonstrate the provision of a >20V APD bias through a shared energy reclamation circuit at the optical data plane. We find a penalty of 0.2 dB with respect to electrically-supplied APDs.
